[Effect of isosorbide dinitrate in relation to posture and age].

Rapid tilting into the 90 degrees upright position after 20 mg ISDN sublingually demonstrates a better orthostatic tolerance of the older group (in spite of a lower cardiac output) in comparison to the younger one. This can be explained by a higher tone of the resistance vessels and a stronger stretch resistance of the arteries of the elastic type (and probably of the veins), which are opposing the hydrostatic effects of orthostasis and guarantee a minor shifting of blood to the lower extremities. The increase of rigidity of the blood vessels with aging declares the better drug resistance of the older group but also points - on the other hand - to the borders of ISDN therapy.

[Isosorbide-5-mononitrate (mono mac) in the prevention of bleeding from esophageal varicose veins in patients with liver cirrhosis].

Varicose esophageal veins bleeding is one of severe complications of hepatic cirrhosis. This complication is effectively managed with combination of beta-blockers with nitrates. Of the latter, optimal is isosorbite-5-mononitrate (mono mac). Its minimal risk of development of nitrate tolerance and pharmacokinetics does not depend on hepatic or renal function. A single dose of mono mac varies from 10 to 50 mg. The individual dose is selected by a fall in systolic blood pressure at rest (by 15-20 mm Hg) above 100 mm Hg. In appearance of serious headache nitrates are followed by beta-blockers monotherapy. It is inferred that isosorbite-5-mononitrate (mono mac) is effective in prophylaxis of hemorrhage from varicose veins of the esophagus both in beta-blockers and as monotherapy when beta-blockers are contraindicated.

[Isosorbide dinitrate in coronary heart disease. Effects of a delayed-action preparation during acute load and in chronic use].

The antianginal effectivity of a sustained release isosorbiddinitrate Sorbidilat Retard drug was examined by the number of spontaneous attacks and by ergometry with a constant work load in a double blind trial with cross over technique. An effect on the stress duration, on the ST segment depression, on the "double product", on heart rate, and blood pressure could be proved, which is interpreted as an therapeutic advantage of serum against placebo. The number of spontaneous attacks could be reduced in the verum period significantly. Ergometry every 2 hour after drug adminstration shows an oral effectivity of about 10 hours.
